VALVE FOR l,SEAT-ACTION WATER-CLOSETS.

Application filed August 31, 1914.

T0 all whom it may concern Be it known that I, WILLIAM G. NEWTON, acitizen of the United States, residing at New Haven, in the county ofNew Haven and State of Connecticut, have invented a new and usefulImprovement in Valves for Seat-Action Tater-Closets; and I do herebydeclare the following, when taken in connection with the accompanyingdrawings and the characters of reference marked thereon, to be a full,clear, and exact description of the same, and which said drawingsconstitute part of this application, and represent, in-

Figure 1 a side view of a valve for seataction water closets constructedin accordance with my invention and shown in connection with a watercloset bowl provided with a hinged seat. Fig. 2 is a. vertical sectionof my improved valve detached. Fig. 3 is a sectional view on line L -bof Fig. 2. Fig. 4 is a sectional view on line o-cZ of Fig. 3.

This invention relates to an improvement in valves for seat action waterclosets.

In many of the constructions of valves for seat action water closets thepressure of water is so great that the weight of a child is insufficientto open the valve so as to flush the closet.

The object of this invention is the construction of a valve providedwith a. vent by which the pressure of the water on the main valve willbe released so that a slight pressure on the seat will be suiiicient tooperate the valve.

My improved valve has the usual inlet 2 and an outlet 3 into the bowl 4to which the valve is attached to be operated by a lug 5 secured to thehinged cover 6. lIhe passage between the inlet 2 and outlet 8 is closedby a. main valve 5a provided with a hollow stem 7 which in this case isformed near its upper en d with openings 8. rIhe inlet chamber 9 opensat the bottom` into a. compression chamber 10, the upper end of which isclosed by a packing 11 at the lower end of the valve 5a and the chambers9 and 10 are connected by a by-pass 12 controlled by a screw plug 13.The operating head 14 in line with the lug 5 is connected with averticallymovaible plunger 15 which is coupled with a valve stem 16which extends down through the hollow valve stem 7 and carries a valve17. The valve stem 16 is formed on oppo- Specication of Letters Patent.

site sides with grooves or channels 18. The valve 17 is` forced upwardby a spring 19 as well as by the pressure of water in the chamber 10.

The upper end of the valve casing has applied to it a cup 21 in whichthe operating head 14 is located, and this cup 21 has a flange 22 seatedupon the edge of the cupshaped recess 28 formed in the bowl 4. Provisionfor adjustment is made by providing a nut 24 screwed onto the threadedneck 25 of the casing and this nut rests on the bottom of the recess 23in which there is an opening 26 for the upward passage of the valvecasing. Below the outlet 3 the casing is also threaded for the receptionof a nut 27 which has a bearing on the outside of the bowl around theclearance opening 28. The valve is thus suspended in the bowl.

In operation when the seat 6 is depressed the lug 5 bearing upon thehead 14 forces the plunger 15 downward and thus moves the valve stein 16so as to press the valve 17 away from its seat allowing the water in thecompression chamber 10 to pass through the grooves 18 and openings 8 tothe outlet 3. This removes the pressure in the chamber 10 so that thevalve 5 may be moved downward by the engagement of a shoulder 20 on thestem 16 with the upper end of the valve stem 7. When the seat isreleased a spring 19 forces the valve 17 to its seat and the pressure ofwater closes the valve 5, this pressure also forcing the water throughthe bypass 12 to the chamber 10, also tending to force the valve 5 toits seat. By providing the relief valve it is immaterial what pressuremay be in the chamber 10 as the water pressure in the chamber isreleased by the first part of the downward movement of the operatingmechanism.

I claim The combination with a water closet bowl having a cup-shapedrecess at the rear and clearance openings below said recess, of a valvecomprising a valve casing having inlet and outlet openings, a. mainvalve between the openings, said main valve formed with a hollow stem, arelief valve within the main valve, said relief valve having a stemformed on opposite sides with grooves, an operating head for moving therelief valve prior to the movement of the main valve,
